Can not assign level streaming volume to sublevel

When I try to assign a streaming volume to my sublevel (CargoRoom_Assets in this case) the option is not there for some reason. My streaming volumes are placed in my persisting level and should load with blueprint, my persisting level is set to always load. Anyone knows what the problem might be why my sublevels doesn’t show up in the dropdown when assigning the streaming volume array to my sublevel? I’m using UE 5.0

If anyone has any idea I would be most greatful. Spent oveer a week now trying to figure this out!

This is my streaming volume BP btw.
